I was having a lot of problems with my printer that had another of brand toner.
Great value and I've never had a problem with ink quality!
I have 2 printers that use the same toner so it worked out great for me.
These CF280X cartridge toners are perfectly compatible with my HP Pro 400 M401n printer and seem to be just as bright and vibrant as the name brand toner.
It is my second time to buy these CF280X toners from the seller and they still working great with my HP printer!
2 out of the 4 toner cartridges do not print correctly and have excessive overflow of ink on the paper.
I don't know if the problem was with the delivery or on the manufacturing end.
I do know that I'll never buy this product again.
One was damaged, and my last backup, the fourth one, printed completely black pages.
So I actually paid double the price, and now am awaiting arrival of a new one and my printer is out of service since the fourth one did not work.
